You probably already have a look on this ...

Are you sure the new data is already in your source files? Maybe you could download with overpass api, which is always current. Existing lines will not get any boundary tags from the relation they are member of, but the whole relation is created as a separate polygon with a negative relation ID.

In a spatial database like spatialite this is a straightforward query. Suppose you have the polygons as parcels and the point layer is zoological (and both are spatial tables in spatialite). I'll assume the parcels has a unique id called parcel_id and the species has species_id as well as species_name and entity. The query would be something like: SELECT ...

The process you need to design will have to be developed in several stages. I would start the process by first selecting all polygons less than 100 population and using Spatial Join with the One to Many option for that selection set against itself. This will create the set of adjacent features with insufficient population touching other similar polygons. ...
